DEBIAN-CVE-2026-10536
A use-after-free vulnerability exists in libcurl when an application configures an HTTP/2 stream-dependency tree via CURLOPTSTREAMDEPENDS or CURLOPTSTREAMDEPENDS_E, subsequently invokes curleasyreset(), and finally terminates the handle with curleasycleanup(). During this final cleanup phase, libcurl attempts to access and modify an internal structure that was already freed during the reset operation.
